However, it began to fly far (37 on the front side) and the second outlet
On the terminal end side of 35, the discharge amount is small and it is easy to fly, but since it is near (rear side 38) in the tangential direction, it falls close and is uniformly dispersed on the transfer rack 9 as a whole.

FIG. 5 shows the second embodiment. In the first embodiment shown in FIG. 1, the second discharge port 35 is located slightly inside the starting end of the handling net 7 when compared with the second net of the second embodiment. The substance discharge port 35 is located so as to be displaced from the starting end of the handling net 7 toward the supply side so that the discharged substances can be directly handled by the handling net 7.
It is designed so that it does not hit or collide with a falling object from the handling net 7. Then, a blind plate 40 surrounds the lower part of the starting end of the handling chamber 2, and the second object discharge port 35
Faces below the blind plate 40.

(Operation) Next, the operation will be described.

When the grain culm in the field is mowed, the root of the mowing grain culm is sandwiched by the grain culm feeding device 6, and the tip of the grain is fed from the one side supply port to the handling room 2, the grain culm is transferred by the grain culm feeding device 6. Threshing is performed by the handling drum 3 rotating in the handling chamber 2, and the threshing drops into the wind selection chamber 8 below the handling net 7.

The grain removal dropped from the handling net 7 near the one side supply port of the handling chamber 2 into the air selection chamber 8 drops onto the transfer rack 9 and is sent to the chaff sheave 13 by the swinging transfer rack 9, and the chaff sheave 13
And the screening net 18 below it, the first product is taken out by the first spiral 19. The straw debris that has reached the Straw rack 14 is sieved there, and the second one drops to the second trough 20, while light dust and the like is blown off by the sorting wind from the blower fan 16, and the cross flow suction fan 23 More sucked out of the machine.

Then, the second product dropped on the second receiving gutter 20 is sent by the second spiral 22, and at the terminal end thereof, it is taken over by the second spiral lifting device 24 and fried, and the second discharge port 35. From the transfer shelf 9
It is jumped up by the jumper 34 and reprocessed.

In this case, since the starting end portion 31 of the transfer spiral blade 27 has a receding angle a with respect to the rotation direction and is cut out (fourth
(Fig.), To prevent wrapping of straw chips and the like around the starting end portion 31.

Then, when the root of the grain culm is sandwiched by the grain culm feeder 6 on the front side 37 of the handling room 2 and the tips of the culms are fed to the handling room 2 to thresh, it rotates with the handling barrel 3 and inevitably the rear side. Many fall to 38. On the other hand, since the second discharge port 35 of the second spiral frying device 24 is opened so as to jump out from the rear side 38 of the handling chamber 2 toward the front side, the falling matter from the handling net 7 is dropped. Meet with
The transfer rack 9 tends to accumulate more in the rear 38 part than in the front 37 part.

However, in the present invention, the second discharge port 35 is provided with the opening upper edge 32.
2 has an opening lower edge 33 and the opening upper edge 32 is an inclined edge that advances toward the upper end of the frying grain with respect to the direction in which the spiral shaft 26 of the second spiral frying device 24 rotates. As shown in Fig. 2, when the second iron is bounced off by the rotation of the pop-out body 34, the tangential direction of the starting end side of the second iron outlet 35 has a large discharge amount and is hard to fly, but is far (front side). 37), and the amount of discharge is small and it is easy to fly on the end side of the secondary discharge port 35, but the tangential direction is near (rear side 38), so it falls close and as a whole. It is evenly dispersed on the transfer rack 9.

Therefore, since the falling objects are uniformly dropped on the transfer rack 9, the entire width of the wind selecting chamber 8 can be used for the wind selection, so that the treatment can be efficiently performed.

Moreover, the second spiral-fried grain raising device 24 is normally returned to the inside of the handling chamber 2, but if returned to the inside of the handling chamber 2, the threshing action is affected. Second outlet of
35 is opened in the wind selection room 8 to reduce the load in the handling room 2.

In particular, in the case of a small threshing device, since the distance between the lower surface of the handling net 7 and the upper surface of the transfer rack 9 is short, the second item jumped from the second item discharge port 35 is handled by the handling screen 7. There is a case that it cannot hit far below the front surface (front side 37), and when the leaked material leaks from the handling net 7, the second object jumped from the second object discharge port 35 is hit from above, It may not be possible to fly to the (front side 37), but in the second embodiment, the second discharge port 35 is
Since it is located on the supply side from the starting end of the handling net 7,
The second object jumped from the second object discharge port 35 is blown far away (on the front side 37) without being interfered with by the handling net 7 and the leaked substance leaking from the handling net 7, and is transferred onto the transfer rack 9. It can be discharged uniformly.

(Effect) The above-mentioned known threshing device has a structure in which a second product such as cuttings is fried by a second spiral fried device and discharged from a second product discharge port formed at the upper end thereof. The amount discharged from the second discharge port is large on the lower start side and smaller on the upper end side.

In addition, the low starting end side does not fly far away because of the large amount of emissions, but it becomes a mountain nearby, and the upper high end side fly away because of the small amount of emissions.

In the case of a small threshing device, since the second spiral frying device itself is also short, there is a tendency for it to fly far away, and the phenomenon in which the second flying object hits even the lower surface of the handling net is observed.

Is a swinging wind selecting device 15 having a width, a second gutter 20 provided directly below or obliquely below the outlet of the wind selecting chamber 8, and a front and rear direction provided on the second gutter 20. A second spiral 22, a cylindrical shape extending from the second gutter 20 provided between the rear side 38 of the second gutter 20 and the rear side of the swinging wind selecting device 15 to the swinging wind selecting device 15 No. 2 spiral frying equipment
In a threshing device having 24 and a second product discharge port 35 for discharging a second product to the swinging air selecting device 15 opened on the front side of the upper end of the fried device 24, the second product discharge port 35 is An opening upper edge 32 and an opening lower edge 33, wherein the opening upper edge 32 is a slanted edge that advances toward the upper end of the fried grain with respect to the rotating direction of the spiral shaft 26 of the second spiral fried grain device 24. Since this is a device, the upper edge 32 of the opening of the second food discharge port 35 is the second spiral frying device.
Since it is an inclined edge that advances toward the upper end of the fried grain with respect to the rotating direction of the spiral shaft 26 of 24, it is possible to fly far (front side 37) in the tangential direction on the starting end side of the second discharge port 35, Since the tangential direction on the terminal side of the material discharge port 35 can be made to fall close (to the rear side 38), it can be uniformly dispersed on the transfer shelf 9 as a whole, and the wind can be selected using the entire width of the wind selecting chamber 8. , Can be processed efficiently.

In particular, in the case of a small threshing device, since the distance between the lower surface of the handling net 7 and the upper surface of the transfer rack 9 is short, the handling net 7 and the leaked substance from the handling net 7 are the second ones. Although it becomes a hindrance to jumping, if the present invention is applied to such a threshing device, the second discharge port
The tangential direction on the low starting end side of 35 can be blown far away, and the tangential direction on the high terminating side of the second object discharge port 35 can be dropped close, so the second object can be removed from the handling net 7 and the handling net 7. You can jump without the interference of the leaked leaked material,
It has a rational structure.
